Production/ Fabrication

Sand, recycled glass and other abundantly available materials are mixed to produce molten glass.

The glass is extruded in a hollow tube, then ground into a fine powder and mixed with carbon. It is put into moulds which pass through a cellulating oven which is heated to produce a glass block with millions of hermetically sealed glass cells .

The FOAMGLAS® block is then passed through an annealing furnace to allow carefully controlled cooling of the block. The blocks are then cut to size, tested and packed; quality control standards are rigidly applied under ISO 9001:2008.

The manufacturing process minimizes the use of energy by heat recycling ensuring an ecologically sound insulation product.
